Abstract: The invention provides a system and method that reduces the precision of the manual alignment process. Users select correspondences between projectors or components of a projector, to form a common coordinate. Using models of the display system, and projectors, the common coordinate system can be mapped quickly to the entire display. The process avoids a need to measure screen points, and allows the user to move significantly fewer points. Alternatively, the invention allows introduction of machine-vision style algorithms into manual calibration techniques to improve performance. This overcomes the tediousness of prior systems by introducing models of the display into the manual alignment process, allowing selection of a small number of points on each projector, and avoiding selection of precisely measured screen points. The system conversely finds correspondences between projectors, allowing mapping of the projectors into a common coordinate system, and quick warping of the coordinate system to the screen.
